An interesting aspect of this if Labour do get a majority of >200.
Tories talking shite of course that this will lead to a very left wing, socialist government. In reality, there will be a LOT of new Labour (not New Labour) MPs in seats won from the Tories - seats that traditionally Tory and are fairly small "c" conservative in terms of the constituency profile and electorate. And probably most of these will have fairly small majorities.
It'll be in their interest of course that the new government is very effective, but not necessarily radical in a typical left-wing sense. They will have a tough fight to hold these in the next election, as the Tories probably won't really go much lower than they are now.
Combined with MPs from core Labour areas, and the MPs from the regained Red Wall, it will lead to some interesting dynamics in the PLP.
